Artichia with papular lesions is a rare congenit,al disease characteriezed by the association of alopecia and papular lesions. We report a case of atrichia with papular lesions in 12-year-old. Alopecia of the scalp and eye brows were present at birth. Nurnerous papular lesions are presentation the trunk, buttock and inguinal area. The histopathologic iinding of a papular lesion showed ker till-filled cyst, and eruptive vellous hair cyst. The patient showed reticulat.ed hyperpigmentation on the hands and feet in addition to the characteristic feature of atriclia with papular lesions.

BACKGROUND: Several reports have demonstrated that TGFalpha and EGF are mitogenic for keratinocytes. Whenther its expression on epithelial tumors is a marker of malignancy or signifies an important step in the development of neoplasia is poorly understood. EGF receptors are also present in normal epidermis and epithelial tumors but their physiological roles are not yet understood. OBJECTIVE: Our purpose was to examine the staining patterns of TGFalpha, EGF and EGF receptors on the npithelial tumors of the skin, and to investigate kinetics of expression of EGF receptors. METHODS: We performed immunoperoxidase staining(ABC technique) with monoclonal anti-TGFalpha antibody, polyclonal anti-EGF antibody and polyclonal anti-EGF receptor antibody on the formalinfixed, paraffin-embedded tissue specimens of benign, premalignant and malignant skin tumors. RESULTS: The density of the expression of TGFalpha and EGF was not correlated with the degree of the malignancy of the epithelial tumors and is neither constant in any kind of the tumors. However the infiltrative type of basal cell carcinoma(BCC) is stronger that its solid type on the expression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. pression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. Focal TGFalpha immunostaining was seen in three of 10 squamous cell carcinomas(SCC) and four of 10 BCCs. TGFalpha immunostaining was absent from the outermost one to two layers of tumor lobules of all keratoacanthomas. The specimens which increased the expression of TGFalpha and EGF tended to decrease the expression of EGF receptor. CONCLUSION: These data suggest that the density of immunohistochemical expression of TGFalpha and EGF may be not dependent on the differentiation of tumor cells, and the pattern of immunohistochemical expression of TGFalpha can differentiate SCC from benign tumors such as keratoacanthoma. FGF receptor may be occupied by both of TGFalpha and EGF. With the receptors being occupied, a down regulation of the receptors may occur which results in decreased EGF receptor expression.

Puromycin aminonucleoside (PAN) nephropathy was induced in a group of Sprague-Dawley rat by a single dose of intraperitoneal injection to study an ultrastructural alteration of glomerular anionic sites by stain with polyethyleneimine (PEI) as a cationic probe and to examine whether proliferation of podocytes occur by immunohistochemical stain for proliferating cell nuclear antigen (PCNA). The experimental rats developed proteinuria three days after PAN injection. Electron microscopic studies of glomeruli showed the loss of epithelial foot processes, formation of cytoplasmic vacuoles, microvillous formation and increased numbers of lyso- somes in the cytoplasm of podocytes. PEI method seems to selectively stain heparan sulfate proteogly-can in basement membrane and has been widely used to evaluate the changes of basement membrane in human disease as well as in experimental work. The anionic sites on the basement membrane with foot process fusion were mostly indistinguishable from those seen in control rats, but focal areas of loss or disarray of anionic sites were noted. The anionic sites were not seen on the basement membrane where the overlying epithelium was detached. It is strongly suggested that proteinuria in PAN nephrosis may be primarily due to a glomerular epithelial lesion, leading to focal disarray of anionic sites or focal defects in the epithelial covering of the basement membrane. The loss of anionic s'ites in the basement mernbrane may be resulted partially from the foot process fusion and mostly from the epithelial detachment. The increased numbers of PCNA positive cells after the injection of PAN is suggestive of possibility of podocytic proliferation or regeneration.

BACKGROUND: Peak expiratory flow (PEF) provides a simple, quantitative, and reproducible measure of the existence and severity of airflow obstructions. Peak flow meters are designed to monitor the condition asthma patients. There are many reports showing the normal predicted value of PEF in other countries. studies on healthy Korean adults have been performed in a relatively small sample number and a lower limit for the normal value was not reported. therefore, an attempt to provide normal predictive PEF value with a lower limit was made. METHOD: The PEF(Mini-Wright peak Flow Meter) measurements and spirometry were done in 233 men and 631 woman without history of respiratory disease. all subjects were non-smokers with no respiratory symptoms. the normal predictive value and its lower limit were developed by multiple regression analysis. The result was compared with regression equations in other reports. RESULTS: The regression equation for the normal PEF predictive value(L/min) is 25.117+4.587×Age(year)-0.064×Age2+2.931×Height(cm) in men in men(R2=0.25), and 146.942-0.011×Age2+1.795×Height(cm)+0.836×Weight (kg) in women(R2=0.21). The regression equation for the lower limit of this value (L/min) is 25.117+4.587×Age(year)-0.064×Age2+1.936×Height (cm) in men, and 146.942-0.011×Age2+1.232× Height (cm)+0.481×Weight (kg) in women. The residuals were normally distributed. The PEF in Korean males was similar to those reported in British and Japanese subjects. The PEF in Korean females was similar to that in British subjects, But higher than the PEF in Japanese subjects. The lower limit of normal value was 71% of normal predictive PEF value in men and 76% in women. CONCLUSION: The normal predictive PEF value and its lower limit was measured from 233 male and 631 female asymptomatic, lifelong non-smoking participants. The normal predictive value was different from those of other studies on Korean subjects. Therefore, further studies are required.

A collodion baby is born with a tough, inelastic parchment-like membrane covering the whole body surface. As the meinbrane fissures and peels, a more characteristic ichthyosiform change is evident beneath the collodion membrane. Uncommonly, normal skin is found under it. We herein present two cases af collodion baby, which were confirmed as a sporadic case of lamellar ichthyosis and a case of lamellar exfoliation of the newborn, respectively, after long-term clinical observation. It is necessary that detailed genetical and molecular biological studies should be perforrned in order to elucidate the fur:damental, molecular changes that cause these dramatic cutaneous changes.

Sixteen patients with prostatodynia underwent clinical studies including urodynamic study, MMPI, and endoscopy. As a control group, another 19 patients with nonbacterial prostatitis and 16 normal man of 20-40 years of age also underwent urodynamic study. The most characteristic urodynamic findings in patients with prostatodynia was a significant increase in maximum urethral closing pressure as compared to control group (mean, 140.9 : 92.1 : 84.1 cmH20). In prostatodynia group, peak urinary flow rate was also significantly decreased as compared to the control group (mean, 12.0: 17.8 : 23.9cc / sec). 11 of 16 patients with prostatodynia was found to have functional outlet obstruction, probably at sympathetically innervated urethral sphincter. And they were treated with minipress and diazepam, of whom 7 showed significant improvement both symptomatically and urodynamically. On MMPI 7patients with prostatodynia showed significant underlying psychiatric disorders, and were treated by psychiatric treatment, of whom 4 showed significant clinical improvement. 2 patients with prostatodynia showed vermontanal pseudopolyp suggestive of prostatitis, were treated with long term TMF-SMX administration, and showed significant improvement. It is suggested that prostatodynia may develop from urethral sphincter overactivity and underlying psychiatric disorders, and that at least some cases with prostatodynia are in fact prostatitis. Uroflowmetry, urethral pressure profile, MMPI study and repeated EPS study may be of help in deciding the treatment plan of prostatodynia.

The association between occupational asbestos exposure and the subsequent development of malignant mesothelioma of pleura is well recognized. We analyzed an asbestos body by energy dispersive X-ray analyser in a case of malignant mesothelioma of pleura who had a history of asbestos exposure 30 years ago. In transmission electron microscope, the asbestos body was composed of a core of refractile thin asbestos fiber bundle and beaded masses of electron-dense iron and protein complex. The core fibers were analyzed as an amphibole type crocidolite fiber [(Na2Fe3Fe2(Si8O22)(OH)2] which composed of high content of silicon, iron and sodium.

Dyschromatosis universalis hereditaria was reported in 1933 by Ichikawa and Hiraga in Japan. This disease is characterized by small pigmented and depigmented mottled macules on the trunk and extremities. We report two cases of dyschromatosis universalis. Case one is a 47-year-old man presented with hypoand hyperpigmented spots on the trunk and extrexities. At about 30 years of age, he started to show pigmentary changes on the back, which became progressively spread to the other parts of the trunk and extremities. Case two is a 27-year-old man with numerous mottled hypo-and hyperpigmented spots on the trunk and extremities. He started to show pigmentary changes on the back about 12 years ago. This pigmentary changes also became progressively spread to the other part of the trunk and extrimities. There were no family history of similar disease. On physical exminations, both patients had hrown rice-grain sized pigmented and depigmented macules without scales and atropy on the trunk and extremites. Fontana-Masson stains revealed decreased and increased melar in granules in the basal cell layers in the hypopigrnented and hyperpigmented lesions respectively.

Idiopathic progressive atrophoderma of Pasini and Pierini(IPAPP) is charcterized by sharply dermatcated, atrophic and slate-gray to brownish patches. We report a 17-year-old female with well-defined, atrophic, and brown colored patched on the abdomen, flank, and back. Histologic finding showed marked thining of dermis with thichening of collagen fibers and fragmentation of elastic fibers.

The pulsed laser lithotripsy has been used in the treatment of urinary calculi. We treated 153 patients of stones, via the pulsed dye laser(Technomed Pulsolith) with 7.5 and 6.5 F. rigid ureteroscope between January 1992 and January 1995. Stones were in bladder(4 cases), upper ureter(17), mid ureter(31) and lower ureter(101). The laser lithotripsies were applied for impacted stones and relatively large stones(more than 6 mm) The success rates according to location were 47%(8/17) in upper ureter, 77%(24/31)in middle ureter, 95%(96/101)in lower ureter and 100%(4/4) in bladder and mean success rate was 86% (132/153). There were 21 failures due to upward migration(9 cases), poor visual field(7), laser resistant stone(3) and malfunction of laser(2). Complications were showed in 28 cases that were gross hematuria(16 cases), ureteral perforation(6), fever(4) and ileus(2), but most of them might be related to ureteroscopy rather than laser, and all of them were resolved with conservative management. So laser lithotripsy is safe and effective method of middle and lower ureteral calculi, and upward migration of stones, the major cause of failure may be resolved by use of extracorporeal shock wave lithotripsy and flexible ureteroscope.
